【正文】 畢 業(yè) 設(shè) 計(jì) 題 目 哈爾濱圖書館七氟丙烷滅火系 統(tǒng)設(shè)計(jì) 院 (系 )別 安全工程學(xué)院 專業(yè)班級(jí) 姓 名 指導(dǎo)教師 職 稱 講師 I 摘 要 圖書館儲(chǔ)藏大量圖書和文字資料，不僅具有經(jīng)濟(jì)價(jià)值，書籍本身更具有重大文化價(jià)值。圖書館本身作為大型公共場(chǎng)所，人員密度大，人口流動(dòng)大，在火災(zāi)方面藏有巨大安全隱患。本次設(shè)計(jì)是根據(jù)國(guó)家相關(guān)法律法規(guī)，對(duì)哈爾濱圖書館進(jìn)行七氟丙烷滅火系統(tǒng)設(shè)計(jì)和火災(zāi)自動(dòng)報(bào)警系統(tǒng)設(shè)計(jì)。在七氟丙烷滅火系統(tǒng)設(shè)計(jì)中，將哈爾濱圖書館合理劃分為 22 個(gè)防護(hù)區(qū)， 對(duì)七氟丙烷滅火系統(tǒng)的設(shè)置進(jìn)行了分析與計(jì)算。最終確定共需噴頭種類 JP— 1 JP— 1 JP— JP— 22共 4 種，噴頭數(shù)量總計(jì) 88 個(gè)。在火災(zāi)自動(dòng)報(bào)警系統(tǒng)設(shè)計(jì)中，將該圖書館劃分為 4 個(gè)報(bào)警區(qū)域和 50 個(gè)探測(cè)區(qū)域并進(jìn)行合理設(shè)計(jì)。共選用了 110 個(gè)感煙探測(cè)器、 311 個(gè)感溫探測(cè)器、 58 個(gè)手動(dòng)報(bào)警按鈕和 54 個(gè)聲光報(bào)警器。在設(shè)計(jì)的結(jié)尾部分，對(duì)哈爾濱圖書館本身的設(shè)計(jì)進(jìn)行了安全疏散驗(yàn)證且驗(yàn)證合格，最大限度保證建筑內(nèi)人員及財(cái)產(chǎn)的安全。 關(guān)鍵詞： 七氟丙烷；火災(zāi)自動(dòng)報(bào)警；安全疏散 II ABSTRACT There is an enormous amount of books and documents in the library. Not only has it economic value, but also has it significant cultural value. Tremendous as the library is, full of population, there must have some hidden safety. The aim of this graduation is to design the FM200 system and the automatic fire alarm system using a legal way in the Harbin library. In the FM200 system, it has been divided into 22 protection parts. According to the accurate analysis and calculation, it has finally decided to choose JP16, JP18, JP20, and JP22 around 88 nozzles. In the automatic fire alarm system, it has been fallen into 4 firealarm areas and 50exploration areas, including 110 smoke detectors, 311 temperature detectors, 58 manual warning buttons, and 54 audible and visual alarms In the end, the design has maximized to ensure the safety of evacuation and property. Keywords:Heptafluoropropane fire extinguishing system。The automatic fire alarm system。Safety evacuation I 目 錄 摘 要 .........................................................................................................................
